Passive Buzzer Module for Arduino – 3.3V-5V Tone Generator

Elevate your electronic projects with this Passive Buzzer Module. Unlike “Active” buzzers that only produce a single monotonous beep when powered, this Passive module allows you to control the sound frequency. By using PWM (Pulse Width Modulation) signals from a microcontroller like an Arduino or ESP32, you can generate a wide range of tones (1.5 to 2.5 kHz), play melodies, or create distinct alarm sounds like the “Star Wars” theme or a police siren.

Low Level Trigger Design

This specific module operates on a Low Level Trigger logic. This means the buzzer activates and produces sound when the signal pin is pulled LOW (Ground) and turns off when the signal is HIGH. This makes it easy to interface with various digital logic circuits.

Robust & Easy to Install

Crafted from high-quality durable plastic, the module is designed for longevity. It features a standard 2.54mm pin pitch for easy breadboarding and a fixed bolt hole for secure mounting in your project enclosure. Whether you are building a digital toy, a reverse parking sensor, or a musical greeting card, this buzzer adds a reliable voice to your device.

Key Features

• Variable Tones: Capable of producing adjustable sounds and melodies via PWM.

Important Product Disclaimer

Please note that the product information provided on our website may not be entirely accurate as it is collected from various sources on the web.

Note

Passive vs. Active: This is a Passive buzzer. It will not make sound if you simply connect it to DC power. You must provide a square wave (PWM) signal to generate sound. If you need a buzzer that beeps continuously just by adding power, please look for our “Active Buzzer Module.”
